Hello,
We are looking to interface an additional Sensor to the SensorTag (CC2541) though I2C as a slave. Can we modify the firmware to map the pins on the P1 header to physically connect to the slave and allow I2C master-slave communication? Are there any specific configurations that we need to do on the TI SensorTag firmware that can help us do this (ie. Where can we set the new sensor's slave address)? We already have the TI debugger and IAR workbench. We are able to modify the code and upload a new firmware on the SensorTag.
